Case Studies

Due to a shortage of ventilators, groups have begun to modify available breathing machines, such as continuous positive airway pressure (CPAP) machines to treat Covid-19 patients. CPAP machines, used to treat sleep apnea, are relatively plentiful. Their conversion provides real-world examples of how individuals, private groups, hospital administrators, public health officials are pitching in to combat the coronavirus pandemic.

PPE shortage has led to additional innovation including the use of vaporized hydrogen peroxide to sterilize N95 masks and other PPEs.

Case Studies

Take a Breather

Rice University engineering students working with a Baylor College of Medicine professor develop a bag valve mask compressor to automate the difficult task of feeding fresh air to patients' lungs, often for hours at a time. The device could help save lives in low-resource settings and in emergency situations.

AES CPAP to PCV Ventilator Conversion Kit

AES Controls, Inc designed a CPAP/BiPAP-to-PCV Ventilator conversion kit specifically to help address the dire ventilator shortage due to the COVID-19 pandemic.

Battelle CCDS Critical Care Decontamination System™

Battelle CCDS™ can decontaminate thousands of N95 respirators using concentrated, vapor phase hydrogen peroxide. Battelle CCDS™ draws on decades of research and is grounded on an FDA study Battelle completed following a 2016 contagion.

Ventilator SOS

Ventilator SOS is a group of engineers, medical doctors, and industry advisers working with faculty and students at UC Berkeley and UC San Francisco to create a streamlined process to adapt these devices for emergency use in local hospitals.


A team of Auburn University engineering professors, students and alumni have successfully re-purposed a standard CPAP machine into a functional emergency ventilator for health care providers potentially coping with ventilator shortages during the Coronavirus Disease 2019 (COVID-19) crisis.

Robertson Ventilators

As states across the country beg for ventilators to help patients suffering with respiratory issues from COVID-19, the University of Mississippi Medical Center is building its own makeshift ventilators with supplies found at a hardware store.
